As part of our commitment to supporting your projects, Stancer Testing-Lab regularly publishes technical articles and application notes highlighting practical uses of our testing services. Our growing library of resources is freely accessible and serves as a reference for the RF engineering community. If you’re looking for information on a topic not yet covered, or need further technical assistance, our engineers are available to help—feel free to contact us for expert guidance..
System impedance Z (Ω)
Wave impedance η (Ω)
Notes:
- Voltage dB units use 20·log10. Power dB units use 10·log10.
- For Voltage/Current/Power conversions you usually need Z.
- For E-field ↔ power density, this tool uses η (default 377Ω).
